We want to creat VPN tunnel to our remote office through a ADSL Broadband connection. I am facing problem for that. We got one static IP address from (ISP). The network connection in my office will be like
ADSL(UT-300R2U) Router/Modem -------CISCO 501 Firewall........Switch......Systems.
ADSL Lan port is connected to firewall outside interface. LAN IP addresses are in the segment 192.168.1.0/24.
Now the problem is my remote team wants to configure VPN on static IP given by the ISP and static IP should be on the firewall outside interface. But the IP address on firewall is publeic ip address192.168.1.3 255.255.255.0 as I explained above.
I know one solution, by putting ADSL router in bridge mode and configuring PPPOe dialer on the outside interface of the firewall. The outside interface of the firewall should get the Staic IP address.
But My team don't want to configure PPPOe dialer on the firewall. Does any body worked on this type of problem. Please advise if anybody have another option to get Static IP address on firewall outside iterface.
Please respond email@example.com
Thanks & Bregds, Datta
